1 '0 all whom it may concern:

Be it known that I, HENRY J. Srmvrs, a citizen of the United States, residing at Beatrice, in the county of Gage and State of Nebraska, have invented certain new and useful Improvements in Molds, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in molds and has relation more particularly to a mold especially designed and adapted for use in the production of blocks; and it is an object of the invention to provide a mold of this general character of novel and improved construction whereby the same may be readily and conveniently adjusted to produce blocks of varying sizes.

It is also an object of the invention to provide a mold having novel and improved means whereby hollow blocks may be produced and whereby the core employed in connection with the mold may be effectively maintained in various adjustments.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved mold whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a view in top plan, with portions broken away, of a mold constructed in accordance with an embodiment of my invention; Fig. 2 is a side elevational view of the mold as herein disclosed; Fig. 3 is an enlarged sectional view taken substantially on the line 3-3 of Fig. 1, with an intermediate portion broken away; Fig. 4 is an enlarged sectional View taken substantially on the line 44 of Fig. 1; Fig. 5 is a fragmentary longitudinal sectional view illustrating a further embodiment of my invention; Fig. 6 is a sectional view taken substantially on the line 6-6 of Fig. 5; Fig. 7 is a view in perspective, detached, of one of the pallets as herein embodied; Fig.

Fig. 9 is a sectional View taken through a wedge constructed in accordance with a further embodiment of my invention; Fig. 10 1s an elevational view of a scraper adapted to be employed in connection with my improved mold; and Fig. 11 is a view, partly in elevation and partlyv in section, illustratng a facing roller adapted to be employed in connection with my improved mold.

As disclosed in the accompanying drawlngs, 1-1 denote longitudinally disposed parallel equidistantly spaced sills resting upon and suitably secured to the transversely disposed sills 2 whereby a supporting frame for my improved mold is afforded, and I find it of advantage to provide the side longitudinal beams 1 with the supporting wheels 3 whereby the mold may be readily transported from one locality to the other as the requirements of practice may necessitate.

The sills 1 and 2 are preferably channel beams and the flanges 4 of the sills 1 are provided adjacent their ends with longitudinally disposed vertically alined slots adapted to receive the wedge or tapered lower extremities 5 of the corner standards or uprights 6.

7-7 denote a plurality of posts substantially L-shape in cross section and overlying the outer faces of the side beams 1 and said posts, except at the ends, are arranged in pairs, as is particularly disclosed in Figs. 1 and 2, and the lower portions of said posts are provided with the longitudinally spaced openings 8 through which the bolts 9 are adapted to be disposed to maintain in operative position the lower separating strips 10 which are disposed transversely of the frame and rest upon the upper flanges 4 of the sills 1 and are spaced longitudinally of said sills in accordance with the desired width of the blocks to he formed. Also secured to the posts 7 adjacent the upper ends thereof and in vertical alinement with the strips 10 are the upper separating strips 11 and said strips 10 and 11 have disposed therethrough in a direction longitudinally of the frame the cores C whereby blocks produced by the mold may be of hollow formation. Interposed between adjacent strips 10 and close ing the space therebetween are the pallets 12- provided at their longitudinal margin withj'the depending flanges l landhaving their end marginal portions adapted to overlie the upper flanges 4 of adjacent sills 1, as'is particularly illustrated'in Fig. 4. 7 The interveningspaces bet-ween the strips 10 and 11 and at opposite sides of the cores Q are closed bythe plates 15, the opposite ends of which being provided with the grooves 16 to receive the-adjacent marginal portions of the strips 10 and 11, as is particularlyshown in Figs. 4: and 8, and as disclosed in Fig. 8, it is to be observed that the plate l5'coinp'rises two superimposed plies of material connected one to the other, as'in'dicated at 17 although it is to be under- I stood that, if preferred, said plate maybe 7 ably .cast.

formed of a single piece of material prefer- "lhef'e'nds of the compartments afforded between-adjacent strips 10 and 11 are closed by the plates 18 which have their marginal portions disposed intermediate-the posts 7 andthe end plates 15 with their lower marginal portions extending below the upper surface of the pallet 12, and for this reason a portion of the side flanges 14: of the pallet is cut-away, as at 19, to permit the upper surface of the pallet to be disposed a predetermined distance above the upper faces of the sills 1 so that the plates 18 may be effectively maintained in applied position.

The lengths of the blocks to be formed are determined by the divider plates 20 whichare interposed between adjacent strips 10 and'll and'fitted within the grooves afforded between adjacent plates 15, each of said end plates 18 and divider plates 20 preferablycomprising a plurality of panels 21 whereby it. will be perceived that the formation of the blocks is facilitated, as it will be understood that the mold or more particularly' the cores (1, upper separating strips 11 and plates 15 will be applied after the plastic material has first been arranged upon the V pallet sl2 between the lower strips 10.

1 As herein set forth, each of thecoresC .is' capable of varying adjustments in cross section in accordance with the necessities of practice and for this reason each of said cores C'CQmPI'lSGS four sections or lengths y of material 22, each of which being substantially L-shape in cross section, as is disclosed in Figs; 4 and 6, with the adjacent walls of these'ctions in overlying relation. The sections 22 are maintained in assembled relanon through the'medium of the wedges w Figs. 1 'and l and 6, comprises a central or body-plate 23 provided with the oppositely 1 5 directed elongated spring flanges 24 bearing against theadjacent faces of the sections 22 and the inner ends of said flanges 24 are rounded, as particularly shown in Fig. 1, to facilitate the insertion of the wedge within the core. The core IV is of substantially the same'construction as the wedge W, except that it is of greater length and has the opposite ends of the flanges 2 1 rounded so as to facilitate its operative coaction with the adj acent ends of alined cores C.

In certain instances, it is desired to have the transverse diameter of a wedge disposed vertically and in such cases I prefer to employ the wedge W as illustrated in Fig. 9 and wherein a central plate or body 25 is employed and having secured to its opposite side faces the supplemental plates 26 from which extend the spring flanges 27. It is to beobserved in Fig. 9 that the plates 26 are detachably-enga'ged with the plate or body 25-so that plates or bodies 25 of varying thicknesses may be employed in accordance with the necessities of practice.

It will be perceived that the openings 8 in the posts 7 permit a vertical adjustment thereof so that, when required, blocks may be produced having superimposed openings therethrough and as illustrated in Figs. 5 and 6, a third separating strip 28 is employed and with which coact the additional cores C and plates 15, said cores C and plates 15 being of a construction similar to that set forthto the cores C and the plates 15.

In order to give proper facing to the blocks, I find it of advantage to employ the scraper blade S as illustrated in Fig. 10, the lower corners of which being notched or recessed, as at 29, to engage the upper mar gins of the strips 11 'or 28 so that said blade will be properly guided. In the event it is desired to give a roughened facing to the blocks, the roller 30 as illustrated in Fig. 11 may be employed and it is to be observed that the ends of said roller is provided with the annular groove 31 adapted to engage the upper marginal portions of the strips 11 or 28.

From the foregoing description, it is thought to be obvious that a mold constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and itwillalso be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.
